Abstract: 640,921. Moulding shoes. BOOTH, J. J. May 5, 1947, No. 12116. [Class 87 (ii)] [Also in Group VII] A mould 13 for forming all-plastic shoes has two outer mould parts, Fig. 1, interengaged by means of guide pins 15 received in slots 16, one of which outer parts is supported by a support 14, and a core 18 positioned in moulding relationship to the outer parts by retaining pins 22a received in openings in the core shank 19. The core 18 is provided with an extension 20 which is slidable relatively to the mould on studs 22 passing through slots 21. The mould is closed, e.g. by a hydraulic ram (not shown) which also causes the mould to be brought into operating relationship with an injection apparatus 10 of known design. To further facilitate manipulation of the parts, compression springs 23 are positioned between support 14 and extension 20 so as to be compressed during the closure of the mould and positioning thereof against the injection nozzle and thereby effect separation of the parts of the mould 13, as the moulding cycle is completed. Passages 24 in the outer mould parts are provided for the circulation of heating media, and the plastic material is injected into the mould cavity 17 through a plurality of nozzles 11 and feeding ports 12. Auxiliary openings 26 are provided to assist the escape of entrapped air and the flow of plastic material. The core 18 may be provided with spaced projections (25, Fig. 3, not shown), for forming perforated designs in the shoe-upper and for effecting spacing of the mould members. On completion of the moulding cycle the pressure on the outer mould parts is released and the compression springs 23 urge the core 18 and an outer part of the mould away from the other outer part, thus exposing a portion of the moulded shoe. The remaining portion of the mould 13 is then removed and the finished shoe manipulated off the core 18. The perforations in the shoe upper, together with grooves formed to extend laterally and longitudinally across the inner face of the insole, provide ventilation to the foot. Reinforcements or inserts may be placed in the mould for incorporation into the shoe, and a collapsable core or retractable projections 25 may be used to facilitate the removal of the moulded product. Variations in temperature, pressure and the number and location of injection points &c. may also be made.
